Impact of Mobility Models on Routing Protocols’ Simulation in Vehicular Ad Hoc Networks

Simulation is one of the most important methods for researching vehicular ad hoc networks(VANET),but simulation results are usually affected by many parameters.This paper addresses the impact of mobility models on routing protocol simulation in VANET.An Urban Taxi VANET(UT-Vanet) was constructed using floating car data.Based on UT-Vanet,a research program concerning the impact of mobility models was proposed,comparing other mobility models including the random WayPoint(RWP) model,and the IDM_IM and IDM_LC models.Simulation results show that these mobility models have a great impact on simulations of routing protocols in VANET.
